Fast delivery thanks.
Nice color to blend with my black colored road bike.
Excellent as always. My trusted bike shop for equipment and mechanics services. Look for Mr Ho, he generously shared the correct way to install the new chain and make fine tunings so that the gear changing will be smooth.
Had my earlier pair exchanged due to size issue. They recommended me this pair and am very happy with it. The exchange was very smooth and no issues at all. Happy to have bought from them.
It’s nice to have a single, fuss-free lube that I can use across my commuter, road, and gravel bikes. Thanks to this large refill bottle I’ll happily continue with RNR Gold for a while longer.
Item was nicely packed and included some grease with it. Easy installation as well. Appreciate the great service and helpful advice too
